Some discoveries are so good, you’re not sure whether to tell the whole world about them or keep them all to yourself. Vestiaire Collective is one of those gems: if you’re not already using it, you’ll thank us for deciding to share.

A curated online buy-and-sell for luxury pieces, Vestiaire is something of a best kept secret for the super-stylish. It’s where you can find those sold-out Isabel Marant wedge sneakers you’d been dying to get your hands on – for less of the price, someone else’s wrong size. Or that perfect Acne leather bomber jacket, worn in just enough to look effortlessly cool and more affordable for it. And unlike other marketplaces where there’s a chance you’ll get swindled into buying fake pieces, the product on Vestiaire has to get past a quality control team who have been trained by leading fashion houses – LVMH, Hermes, Celine and Louboutin amoung them – in how to spot fakes.
